### Planning and Activities

**Day 1 Teaching**

Use five pegs on a hanger and a cloth to model different additions to partition 5.

**Further Teaching with Y2**

Use a number balance to model ‘balancing sums’ to 7, 8 and 9, e.g. 5 + = 6 + 1**Group Activities: T with Y2**

Y1 -- Make ‘snakes’ using five cubes in two colours. Record the additions.

Y2 -- Use number balances to create ‘balancing sums’.

**Day 2 Teaching**

Use six pegs on a hanger and a cloth to model different additions and subtractions. Use a 20-bead frame to show linked pairs to 10 and 20, e.g. 5 + = 10 and 15 + = 20.**Group Activities: T with Y1**

Use the ‘Domino loop’ in-depth problem-solving investigation below as today’s group activity.

Or, use these activities:

Y1 -- Solve a missing eggs problem … or … Make pairs to 6 using egg boxes and modelling clay eggs.

Y2 -- Explore pairs of numbers that add to 20.

**Day 3 Teaching**

Use a stick of cubes and bar models to show pairs to 10 and 20.**Further Teaching with Y1**

Break sticks of 10 in different places; write matching additions.**Group Activities: T with Y1**

Y1 -- Explore pairs to 10, making ‘snakes’ of cubes in two colours or by matching sticks of 10 cubes to bar models.

Y2 -- List all possible additions and subtractions for 10 or 20 to go with a number story.

**Day 4 Teaching**

Use fingers to find pairs to 10 and record additions.**Further Teaching with Y2**

Use a 20-bead frame to explore complements to 20, first adding to the next 10.**Group Activities: T with Y2**

Y1 -- Explore complements to 10 using sticks of cubes and number cards, or by playing number bond snap.

Y2 -- Take a card and say what needs to be added to make 20; record the matching addition and subtraction.

**Day 5 Teaching**

Partition 10 pegs in two colours on a hanger and record the related additions. Hide some pegs and record missing number sentences. Children say how many are hidden.**Further Teaching with Y2**

Write number sentences with symbols standing for mystery numbers. Children work out what numbers they represent.**Group Activities: T with Y2**

Y1 -- Place 10 spots on ladybirds in different ways. Explore all possibilities.

Y2 -- Use number facts to work out how many cubes are hidden under a cup or in a number sentence under sticky notes.
